Maybe that CLR stuff will work. Click to expand... I thought about that...but I'd worry about the opal...I'd think that the CLR would dissolve that as well.

Here is link to Opal composition, which is silica: https://en.wikipedia.org/wiki/Opal And here is link to CLR MSDS which lists the active ingredients: https://clrbrands.com/Jelmar/media/sds/CLR-CalciumLimeRust-SDS-1-16-19.pdf A little additional research should give you the answer.
